I have been feeding TO (Wild & Natural, Ocean Blue, Dakota Bison) to my three (a beagle, a jack russell and a cairn terrier) for well over a year with excellent results. A 4 month old female german shepherd has now joined our family. I haven't seen a lot of comments about TO's (particularly the Wild & Natural) suitability for large breed pups. I know that Innova Evo is not recommended for large breed pups. Any opinions?
